Conventions
• • • •
Dimensions – range instead of absolute dimension where possible Construction and manufacturing tolerances Calculation of percentages Figures – are informational; the text governs!
Great Plains ADA Center
Ranges instead of absolute dimensions Water closet centerline (16 18”) Width of ambulatory accessible stall (35”- 37”) Great Plains ADA Center
Some absolute dimensions remain Transfer shower stall (36” x 36”) and combination transfer/roll in design with seat on front wall (36” deep) measured to center points; manufacturing tolerances recognized Great Plains ADA Center
Conventional Industry Tolerances
• • • •
For field conditions and manufacturing process (not design work) Don’t apply to ranges (min. and max.) For absolute dimensions or where only a min. or max. specified Avoid specifying tolerances (e.g., “36 inches plus or minus X inches”) Design should specify above max. or below min. (to factor in tolerance) Great Plains ADA Center
